Delta slope
The device determines the difference in slope between the last calibration and the penultimate
calibration, and issues a warning or an alarm depending on the setting configured. The
difference is an indicator for the condition of the sensor. An increasing change indicates the
formation of buildup on the sensor diaphragm or electrolyte contamination. Replace the
diaphragm and electrolyte as specified in the instructions in the sensor operating manual.
Zero point
The zero point corresponds to the sensor signal that is measured in a medium in the absence of
chlorine. You can calibrate the zero point in water that is free from chlorine. This improves
accuracy in the trace range.
